Abstract (en)
[origin: WO2019100337A1] Recognizing a region navigable by a mobile platform and pairing topology information for locating the mobile platform, and associated systems and methods are disclosed herein. A representative method includes determining obstacles from sensory data, filtering out non-qualified obstacles, determining a navigable region based on obstacle locations, detecting a road intersection based on obstacle distance distribution, determining the topology of the intersection, and pairing the determined topology with topology information based on map data.
